BOSTON -- Rajon Rondo briefly left the Celtics' win against the Jazz at TD Garden, returning to the bench after spraining his ankle in the third quarter. But the team is listing his status as day-to-day.

“I have no idea,” coach Doc Rivers said after the game, regarding Rondo's availability for Thursday's game against Brooklyn. “With sprained ankles, tomorrow you’ll know more.”

Rondo sprained the ankle with 4:55 to go in the third quarter, when he landed on it awkwardly following a missed layup. He went immediately to the locker room but returned moments later. Rondo will be re-evaluated before the Celtics take on the Nets in Brooklyn.

Rondo had six points and 10 assists on the night for Boston, which got another good outing from Leandro Barbosa backing up Rondo. Barbosa had 16 points in 23 minutes backing up Rondo.

The Celtics, already without shooting guard Avery Bradley, loaded up on guards in the offseason, and Rivers said he expects that depth to pay off. If Barbosa gets more minutes because of Rondo’s absence, that playing time has been deserved.

“He’s earned it,” Rivers said. “I tell everybody, ‘Listen, we sign you, and you come, and there’s no guarantees that you’re going to play. But if you earn it, you get to play.’ And he’s earned it. He deserves to play.”
